SOUTH AFRICAN MILITARY BADGE ?: RARE ?: WHICH ONE IS IT ? IN SOUTH AFRICA

Silver colour badge in first two photos only. So far, I just can't find out which badge this is, or even one single other image of this badge on the net. It is genuine it seems, what is this badge ?. Nobody can tell me. The original owner is no longer alive, so I can't ask him. It was collected in Zimbabwe. It is similar to the Prince Alfred's Guard badge in the third image. The fourth image is that of a Zulu shield. So it seems to be South African. There were quite thick pieces of bare copper wire cut off from the clasps. I would think it is anything pre-1950. Feel free to let me know. As per photos. Sold as is.
